Remove invalid Entries from "Add or Remove Programs"

Sometimes when you remove a program, corresponding entry
in the Add or Remove Programs listing may not be removed. This may be due to incomplete uninstall or bad quality
uninstaller.
You can use this method to manually remove the invalid entries from the Add or
Remove Programs applet.

Safer than using the below method is using the Windows Installer Cleanup Utility.



Steps:

1. Open Registry Editor. (Start > Run > Regedit) [ No Run? / Regedit Disabled? ]

2. Get to this location:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

3. Export (Backup) that key.

4. Open the tree, you can see many branches. Click on every branch and
see the right pane. You can see the corresponding applications name in
the key DisplayName.

5. If you have the DisplayName value for any branch as the name of the application that you have removed, then delete that key.

Note:If you have accidently deleted any of needed key, you can import it from the file you have exported. Double click on the file and click Yes and then OK.
